Dr. Christophe Lembregts investigates how consumers process numerical information and how it affects decision making. By building on research on numerical cognition, linguistics and decision making, he aims to advance knowledge of how consumers construct evaluations based on numerical information and which contexts increase consumers’ reliance on numerical information. He published his research in international journals such as the Journal of Consumer Research, Journal of Consumer Psychology, Journal of Marketing Research and Journal of Economic Psychology. He is the recipient of various grants such as a FWO doctoral grant from the Belgian government and a NWO Veni grant from the Dutch government.  Dr. Lembregts obtained his PhD at Ghent University (Belgium) and joined Rotterdam School of Management in 2015. Dr. Lembregts teaches "Marketing Management" (BA 1), "Customer Experience Management" (MA) and coordinates the "Honours Class in Marketing Management" (MA).

The Marketing group at Rotterdam School of Management, Erasmus University seeks a highly motivated PhD student looking to study research questions in the domain of consumer behavior. Strong applicants are motivated to conduct novel research within the field of consumer behavior, typically have a background in psychology, business, statistics, or a related field, and desire to pursue careers as world-class academic researchers. The project will enable the PhD student to develop new theories about consumer behavior and/or psychology and test these theories utilizing quantitative research. Students define and execute their own projects in consultation with their advisers, and thus need creativity, self-direction, and a passion for scientific research.
